Ok lets talk a little bit about the CE4s that came with my starter. At first I liked it, threw my first flavor in there and boom sweet worked out i liked it, at first. then when i realized how slightly difficult it would be to change flavors i was disappointed. One of the alluring factors of vaping for me was being able to try all these amazing flavors. I felt like I was gonna have to do to much in order to switch flavors. I only used them for two weeks. If i had to make a recommendation i would say sure to start with, but not as a permanent fixture in your collection. If you can get new vapors to start with something a little better awesome if thats not an option then theyll work for a bit.
